While Coronavirus New studies have found that while they may be able to survive on beds, floors, and other surfaces near COVID patients, they are unlikely to be passed on to others.
University researchers California The San Diego Medical College wiped the surface of the COVID patient’s room before, during, and after the occupation. Coronavirus was found in about 13% of the samples.
None of the healthcare professionals caring for patients in this study tested positive, despite frequent contact with their surfaces. This indicates that surface permeation is rare and PPE is working.
The study also found a new link between coronavirus and the types of microorganisms that may be associated with cardiovascular disease and severe COVID.

At the beginning of the pandemic, public health experts warned against surface infections or the spread of the virus through particles left on doorknobs, desks, and other common items.
“Wash your hands” has become a common mantra. The hand sanitizer has been sold out. The New York City Subway was closed for overnight cleaning.
But now, surface transparency Rare phenomenon For the coronavirus. Instead, the virus usually spreads into the air through either large particles that are released when an infected person sneezes or coughs, or small particles that can travel long distances.
New studies add evidence that surface infections are rare and provide new insights into how coronavirus shares space with bacteria.
Researchers at the University of California, San Diego Medical School have investigated what the coronavirus does on the surface by wiping the patient’s room.Research Published on Tuesday In the journal Microbiome..
Researchers collected nearly 1,000 samples from 16 patients with confirmed cases of COVID, 10 healthcare professionals caring for those patients, and hundreds of locations inside and outside the hospital room. Did.
These 16 patients were hospitalized for up to 3 weeks. Researchers collected samples before, during, and after admission.
From these surfaces they sampled, researchers found that 13 percent of the sites had enough coronavirus to be picked up by PCR tests.
Samples taken from the floor next to the patient’s bed and just outside the room were most likely to contain the coronavirus, with prevalences of 39% and 29%, respectively.
The prevalence of the surface inside the hospital room (excluding the floor) was 16%. These surfaces contained ventilation buttons, keyboards, and door handles.
Surface samples had much lower concentrations of coronavirus than samples actually taken from patients using classic nasal swabs and stool screening.
These low concentrations indicate that the coronavirus present on the surface of the room is less likely to infect anyone than the coronavirus particles sneezing from the patient.
Floor locations near the patient’s bed were likely to be COVID positive
In fact, this study did not find any coronavirus infections caused by surface infections.
Despite caring for COVID patients and collecting samples, no healthcare professional tested positive throughout the study. This suggests that personal protective equipment and safety training reduce the risk of infection for health care workers.
“This is huge at so many levels,” said Dr. Daniel Sweeney, a physician for critical care and infectious diseases at the University of California, San Diego, and the lead author of the treatise. In the statement“We need to know if our personal protective device, PPE, is appropriate. Fortunately, we’ve found that masks, gloves, gowns, face shields, etc. actually work. This pandemic It was a pandemic, but it can be exacerbated if health care workers are infected, especially if the reason is unknown.
In addition to the coronavirus itself, researchers have investigated the microorganisms that interact with the virus.
The microbial rothia is often found in coronaviruses, indicating that bacteria and viruses may have formed some partnership.
Microbes live inside the human body-many of them are in our digestive system-and outside the body. They can have a significant impact on the body’s ability to fight illness.
Researchers have examined the genetic composition of all microorganisms found in coronavirus samples.
“We feel like we’ve lived with this virus for a long time, but research into the interaction of SARS-CoV-2 with other microorganisms is still new and there are still many questions,” says Sarah Allard. The doctor says. , Another lead author of scientists and research at the University of California, San Diego.
“The more we know how a virus interacts with its environment, the better we understand how it is transmitted and how it is best to block it to prevent and treat the disease. I can do it.”
In particular, Allard and her team often found the virus along with certain types of bacteria called viruses. RothiaThis bacterium was more common in COVID-positive samples than in other non-COVID samples.
Is Rothia Species are commonly found in the human mouth, but can also invade the digestive system.
Researchers at the University of California, San Diego have discovered that the bacterium is associated with cardiovascular disease. Patients who had cardiovascular disease before getting COVID Rothia With their sample.
“Why that relationship?” Allard asked. “Do bacteria help the virus survive, or vice versa? Or are these bacteria just associated with an underlying condition that increases the risk of severe COVID-19 in the first place? ? It’s an area for future research. “
The findings of this study on surface infections are not new, but the microorganisms that have become familiar with the coronavirus are worth further study. By examining these viral and microbial partnerships, researchers can develop more successful COVID therapies for future patients.
